IMPROVEMENT IN vnvuu'oc ARBON-BUR NERS.

Specification forming part of Letters :Butent No. 198,048, dated July10, 1877; application filed June 14, 1877.

To all whom it may concern.-

Be it known that we, WILLIAM STEWART, ROBERT J. STEWART, and CHARLES W.MAKEPEAGE, of Paterson, in the county of Passaic and State of NewJersey, have invented certain new and useful Improvements inHydrocarbon-Burners for Heating Steam- Boilers and other Furnaces, ofwhich the following is a specification:

In the drawings, Figure 1 represents a horizontal section of a furnaceconstructed according to our invention. Fig. 2 is a transverse sectionof the same. Fig. 3 is a like section of a modification thereof.

Similar letters of reference indicate like parts.

Our invention relates to an apparatus for heating steam-boilers andother furnaces; and consists in a box which is closed at the top, andprovided with holes in the lower part of its sides and bottom; alsoprovided with a filling of asbestus or other absorbent, and refractorymaterial, and with afeed-pipe, which extends through the interior of thebox in a horizontal direction in such a manner that, if the feedpipe isconnected to a tank containing petroleum or any other suitablehydrocarbon liquid, the liquid can thereby be ejected in or upon thefilling in the box, so that the liquid is caused to permeate suchfilling, and thence ooze out through the holes in the sides and bottomof the box, and, if it is ignited at these holes, the box is therebyheated, the liquid is vaporized, and a powerful flame issues from eachof the holes.

In the drawing, the letter A designates a box, which, in the exampleshown in Figs. 1 and 2, forms the body of a grate-bar, but which may bemade detached from the gratebar, as shown in Fig. 3. This box isprovided with a cover, 0, which is firmly secured in position byscrew-bolts or other suitable means, and which can be taken off, so asto obtain access to the interior of the box. In the lower portion of thesides and in the bottom of the box A are formed a series of holes, a.The said box A is filled with loose asbestus fibers, pulverizedpumice-stone, or any other suitable refractory and absorbent material,and in it is placed, horizontally, a pipe, D,

which is perforated and extends throughout the entire length of the box.

Said pipe may be provided with a series of lateral branches, as shown inFig. 2, and it connects with a suitable tank or vessel containingpetroleum, or any other suitable hydrocarbon liquid, the communicationbetween the tank and the pipe D being controlled by a suitablestop-cock.

If the grate-bars are made hollow they are all connected to one and thesame oil-tank.

When .our heating apparatus is to be used in a furnace with ordinarygrate-bars, one or more boxes A, filled with asbestus, are placedloosely on the grate-bars, and the pipes contained in such boxes areconnected to an oiltank.

When the communication between the oiltank and the pipe D is opened,the-hydrocarbon liquid issues from the perforations of the pipes D infine jets, and spreads rapidly and uniformly throughout the asbestus orother filling, whereby the same is carried to the perforations in thesides and bottom of the box A, and by igniting the liquid issuing fromthese perforations a very intense heat can be produced and atcomparatively little expense.

The hydrocarbon liquid, after having permeated the refractory andabsorbent material in the box A, sinks down and oozes out through theholes in the-sides and bottom of saidbox, and if it is ignited at theseholes the box soon becomes heated to a high degree, so that thehydrocarbon liquid becomes vaporized, and a powerful blazeissues fromeach of the holes, forming a large flame which entirely surrounds thebox and produces a very intense heat.

In our apparatus all the holes are situated in the lower'portions of thesides and in the bottom of the box, and if a proper supply of liquid iskept up a portion of such liquid issues from each of theholes, and allthe liquid introduced into the box A is consumed.

Our heating apparatus can be used to great advantage in locomotive andother steamboilers, in kilns for burning brick, and, in fact, in allplaces where it is desirable to produce an intense and rapid heat.

The supply of oil to the horizontal pipe is,

of course, regulated, so that it is all consumed and none wasted in theash-pit.

It will be evident that by having the openings in the bottom of the box,the latter is uniformly heated throughout, and as the oil in the box istransformed into vapors, it issues from all the openings in powerfuljets, so as to produce an immense flame; and, further, by extending thefeed-pipe through the box in a horizontal direction all the openings inthe box are uniformly and evenly supplied with 01 What we claim, anddesire to secure by Letters Patent, is-

An apparatus for heating steam-boilers and other furnaces composed of abox, A, closed at its top and provided with holes in the lower part ofits sides and in its bottom, a filling of asbestos or other absorbentand refractory material, and a feed-pipe extending in a horizontaldirection through said box, all constructed and operating substantiallyas described.

In testimony that we claim the foregoing we have hereunto set our handsand seals this 11th day of June, 1877.
